This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X170-50S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SUJ Adjustable Cylinder SUJ32X170-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X170-50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 170mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X170-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X170-50S
The AirTAC SUJ32X170-50S is a double-acting double-rod profile cylinder with an adjustable extend stroke. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, providing a usable range of 120-170 mm from the 170 mm nominal maximum. The extruded aluminum profile barrel is shorter than a standard cylinder of the same bore. The stop screw sets the end position and is not a load lock.
This SUJ32X170-50S model is discontinued; the direct replacement is the SAUJ32X170-50S, retaining the same force, port, and FA/LB mounting. Note that the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. A plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X170-50S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X170-50S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×170 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SUJ Adjustable Cylinder SUJ32X170-50S Is Used
Variable Length Gauging
Trimming the extend stroke by up to 50 mm on-site allows precise positioning of gauging arms without machining custom spacers.
Adjustable Clamping Force
Dialing in the extend stop between 120-170 mm sets the exact clamping reach for varying part widths on a single fixture.
Feed Stroke Tuning
Fine-tuning the extend endpoint on-site accommodates different material lengths in automated feed mechanisms.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X170-50S with the SAUJ32X170-50S
To replace the discontinued SUJ32X170-50S, use the direct replacement SAUJ32X170-50S which matches the 32 mm bore, 170 mm stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 50 mm adjust window if your fixture needs on-site extend tuning between 120 and 170 mm; this stop screw sets end position but is not a lock. For -S magnet models, swap the legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG on the SAUJ. Because the stroke is 170 mm, ensure side-load alignment is within tolerance to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X170-50S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUJ Adjustable Cylinder SUJ32X170-50S FAQ
Yes, the SUJ32X170-50S is discontinued. The direct replacement is the SAUJ32X170-50S, which shares the same 32 mm bore, 170 mm stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. You must upgrade the sensors from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG.
The external stop screw provides a 50 mm adjust window, allowing you to shorten the extend stroke from the 170 mm maximum down to 120 mm. The stop sets end position and is not a load lock.
